I. Introduction of T ≤ Vus Certification in USA    

The T ≤ Vus certification mark provides customers with a clear and straightforward approach to product safety, enabling their products to successfully enter the U.S. Market. At present, T ≤ Vus certification is second only to UL certification in North America. In order not to be inconsistent with the name of UL Meihua, the NRTL certification issued by T ≤ V organization is also called T ≤ Vus (USA).     



II. Importance of battery T ≤ Vus certification    

At present, the battery testing certification, UL standard testing requirements are the most stringent, the most testing steps, recognition is also the highest. However, UL institutions issued the highest certification costs, most of the domestic battery enterprises can not accept the price, the cost is too high. T ≤ Vus certification is a German T ≤ V organization strictly in accordance with the UL standard for battery products testing, but the cost is only less than half of the UL certification, can also prove the quality of battery products, so that customers can trust to buy, in North America market also has visibility, market share has been greatly improved.
